Embodiment Construction

[0025] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] A kind of translation motion device of scissors boosting provided by the present invention, that is, the scissors boosting adjustment device is as follows: figure 1 As shown, the adjusting device can effectively reduce the demand for driving force and reduce the weight of the adjusting device. The adjustment device is composed of an equal load structure 11, a rod group module 12 and a drive module 13, and the two adjustment devices are respectively arranged on both sides of the adjustable plate.

[0027] like figure 2 As shown, the driving module 13 is mainly composed of a motor, a motor reducer 1, a synchronous pulley 2, a lead screw 3, a lead screw nut 4, a fixed side support of the lead screw, and a dovetai...

Abstract

The invention relates to a scissor force-increasing translational motion device, which belongs to the technical field of wide speed range combined power. The present invention can effectively reduce the requirement on the output performance of the driving device through the scissors booster mechanism, thereby increasing the power-to-weight ratio of the mechanism, and realizing the purpose of weight reduction of the large-load adjustment mechanism; the load-sharing structure effectively avoids the occurrence of heavy loads at the hinged position. The problem of large deformation and excessive stress.

Description

technical field [0001] The invention belongs to the technical field of combined power in a wide speed range, and in particular relates to a translational movement device for scissor force boosting. Background technique [0002] The development of wide-speed combined power has become the weight strategic development direction of the world's major countries in the field of aerospace. As one of the important components of the air-breathing combined engine, the design of the intake duct plays a key role in the performance of the entire propulsion system. It is difficult to achieve the goal of efficiently providing the required airflow to the combustion chamber with the intake port of a fixed geometry under different Mach number conditions. The airway is designed to be variable geometry and adjustable. The variable geometry inlet can fully coordinate the moving parts during the flight to meet the compression requirements of the incoming flow under different Mach numbers, and at...
